Benefits of technology

[0012]The main objective of the present invention is to provide an electric nibbler that can be used safely, conveniently and quickly.

Problems solved by technology

1. When a sheetmetal is cut with the conventional electric nibbler (60), the metal filings are produced by the punch pin (63), and this will cause material waste and the working space dirty.
2. Furthermore, the momentum of the punch pin (63) is large, and the user cannot control the conventional electric nibbler (60) easily and may get hurt by the punch pin (63).
3. When the sheetmetal is cut with the conventional electric nibbler (70), the sheetmetal cannot be supported by the blades (73, 74), and the cutting speed of the conventional electric nibbler (70) is slow so the conventional electric nibbler (70) is inconvenient in use.
4. When the blades (73, 74) of the conventional electric nibbler (70) are worn down, to change the worn blades (73, 74) is difficult and troublesome.

The battery package is detachably attached to the battery seat of the handle. The front cover is mounted securely to the handle and has a mounting bracket and a housing. The base is connected securely to the housing and has an upper segment and a lower segment. The lower blade is connected securely to the lower segment. The drive device is mounted in the handle and a drive shaft. The transmitting device is connected to the drive device and has a connecting tube, a transmitting shaft, a drive axle, a gear wheel, a crank and a piston rod. The upper blade is connected securely to the bottom end of the piston rod.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an electric hand tool, and more particularly relates to an electric nibbler that can be used safely, conveniently and quickly.[0003]2. Description of Related Art[0004]With reference to FIG. 7, a conventional electric nibbler (60) is used to cut a sheetmetal and has a handle and an operating head. The handle has a front end, a rear end and a power cord. The power cord is connected to the rear end of the handle, is used to conduct electricity from an outlet to the conventional electric nibbler (60). The operating head is formed on the front end of the handle and has a bottom, an extending shaft (61) and a bottom base (62). The extending shaft (61) is protruded on the bottom of the operating head and has a lower end and a punch pin (63). The punch pin (63) is movably mounted on the lower end of the extending shaft (61). The bottom base (62) is connected securely to the extending shaft (61) ...
